The above procedure applies to an installation using the default repository repo.magento.com. The extension must therefore be "purchased" on Magento Marketplace first, otherwise it can't be downloaded from the repository.

Installation from ZIP package (artifact)

If you want to install the extension from a ZIP package, execute this command before all commands shown above:

composer config repositories.<extension> artifact /path/to/folder/

Note: The path must point to the folder which contains the ZIP, not to the ZIP file itself. Leave out (omit) the ZIP filename at the end!

Then execute the other commands shown above, same as for installation from Magento Marketplace.

Hints

The values for "vendor" and "extension" depend on the actual Magento extension. Please refer to the Readme file or PDF documentation for details.

During installation, Composer might ask for a user and password. You must use the public and private key of the user which was used to purchase the extension.

The "list of locales" depends on the languages in the shop. Example: "en_US en_GB fr_FR de_DE it_IT" etc.
